DS32EL0421, DS32ELX0421 125 – 312.5 MHz Serializer with DDR LVDS Parallel LVDS Interface PRELIMINARY May 9, 2008 DS32EL0421, DS32ELX0421 125 – 312.5 MHz Serializer with DDR LVDS Parallel LVDS Interface General Description The DS32EL0421/DS32ELX0421 is a 125 MHz to 312.5 MHz (DDR) serializer for high-speed serial transmission over FR-4 printed circuit board backplanes, balanced cables, and optical fiber. This easy-to-use chipset integrates advanced signal and clock conditioning functions, with an FPGA friendly interwww.DataSheet4U.com face. The DS32EL0421/DS32ELX0421 serializes up to 5 parallel input LVDS channels to create a maximum data payload of 3.125 Gbps. If the integrated DC-balance encoding is enabled, the maximum data payload achievable is 2.5 Gbps.
